Hi all. Just got my brand new shiny iMac yesterday. Find that the wired mighty mouse is rather sluggish at times. I've set the tracking speed to the fastest. The problem is the mouse tracking sometimes fast and slow, making me move my hand more than necessary just to move the cursor across the screen. Is this normal? Would my 1GB RAM caused such a sluggish mouse? This mouse is hurting my wrist already.

Problem solved. Mighty Mouse works great on a black dark surface. Was using an A4 paper that there rest of my cheapo mouse has no problem with.

After a few days using the mighty mouse, I have to admit the novelty sort of wears off. I often right-clicked when I wanted to left-clicked. A single hard shell body of the mouse doesn't help me to left-click faster than I used to.

Erm.... do you know there is 3rd button (click the scroll button) and 4th button (on the side of the mouse) and it is configurable? I've set my 3rd button to launch Expose and 4th button to launch Spaces.

And you can set the scroll mouse to scroll 360 degrees. Handy if you need to photoshop some large images.
